在javascript警报内写php

Question

I write PHP inside JS in the following way

alert(<?php echo __("Error-login") ?>);

echo__("Error-login") correlates with an xml to translate in two languages ​​with symfony, but now it does not work.

How do I fix this?

Answer 1

您在alert()调用中缺少引号。

alert('<?php echo __("Error-login") ?>'); 

Answer 2

Your line becomes

alert(Error-login);

As you can see, you are missing the quotes:

alert('Error-login');

If somebody uses quotes in the translation, this will also generate an error:

alert('Error's are here');

So you need to escape single quotes before you pass it to Javascript.

Answer 3

You must name file as. Php. Because JavaScript doesn't support php code as inside.
